Why do we go through this? Why do we eat healthy? Why do we exercise? Why do we go to school? Why do we GAL? Why do we get out of bed in the morning? Because at the end of it, if we choose, we are better for it.
Of course you have the choice to let go and move on. There are no guarantees that the next person's issues will be better or worse than your W's.
For me, I chose to stay and keep things as simple as possible for my kids. I hope in the end it is the best thing for me too. If it isn't, then I'll have another choice to make. But I like to believe I'm a stronger person for going through all this.
One last quick thought...I strongly feel that our society in general is far too disposable in every aspect, and certainly that shows in divorce rates. I know you've worked hard LN...harder than so many others who have just thrown in the towel, so I'm not accusing here...just observing.
